The Joy-Car is an autonomous education robot based on micro:bit and offers a modular robotics learning kit. With the help of the detailed manual, all assemblies and their functions as a whole machine are explained, as well as details of programming and codes. Sensors such as line tracking, ultrasonic, infrared and wheel speed sensors enable functions like autonomous driving and even control via BT using a second, separate micro:bit. The additional equipment simulates turn signals, lights, reversing light and horn, thus rounding off the experience of an autonomous robot car. By using addressable LEDs, individual lighting scenarios can also be realized.
